A Living Foundry for Synthetic Biological Materials: A Synthetic Biology Roadmap to New Advanced Materials

Society is on the cusp of harnessing recent advances in synthetic biology to discover new bio-based products and routes to their affordable and sustainable manufacture. This is no more evident than in the discovery and manufacture of Synthetic Biological Materials, where synthetic biology has the capacity to usher in a new Materials from Biology era that will revolutionise the discovery and manufacture of innovative synthetic biological materials. These will encompass novel, smart, functionalised and hybrid materials for diverse applications whose discovery and routes to bio-production will be stimulated by the fusion of new technologies positioned across physical, digital and biological spheres. This article, which developed from an international workshop held in Manchester, United Kingdom, in 2017 [1], sets out to identify opportunities in the new materials from biology era. It considers requirements, early understanding and foresight of the challenges faced in delivering a Discovery to Manufacturing Pipeline for synthetic biological materials using synthetic biology approaches. This challenge spans the complete production cycle from intelligent and predictive design, fabrication, evaluation and production of synthetic biological materials to new ways of bringing these products to market. Pathway opportunities are identified that will help foster expertise sharing and infrastructure development to accelerate the delivery of a new generation of synthetic biological materials and the leveraging of existing investments in synthetic biology and advanced materials research to achieve this goal.

Interleukin1 influences ischemic brain damage in the mouse independently of the interleukin-1 type I receptor

The cytokine interleukin-1 � (IL-1�) contributes to ischemic, excitotoxic, and traumatic brain injury. IL-1 � actions depend on interaction with a single receptor (IL-1RI), which associates with an accessory protein (IL-1RAcP), and is blocked by IL-1 receptor antagonist (IL-1ra). Here we show that in normal mice [wild-type (WT)], intracerebroventricular injection of IL-1ra markedly reduces (�50%; p � 0.01) ischemic brain damage caused by reversible occlusion of the middle cerebral artery, whereas injection of IL-1 � exacerbates damage (�45%; p � 0.05). Mice lacking IL-1RI [IL-1RI knock-out (KO)] exhibited ischemic brain damage that is almost identical to that of the WT (infarct volume 43.7 � 6.1 and 46.2 � 6.2 mm 3, respectively), but failed to respond to injection of IL-1ra. However, injection of IL-1 � (intracerebroventricularly) exacerbated ischemic brai
